Music was such a huge part of the show that the fictional club Tric was written into the show in Season 2 so the writers could feature more bands and artists.
Chad Michael Murray was the first actor to be cast in the show, though creator Mark Schwahn originally wanted him to play Nathan, having seen him in bad guy roles before. But Murray himself wanted to play Lucas, because he felt that the character had a back story he could connect more to, since he also experienced being abandoned as a child.

Cast members Chad Michael Murray (Lucas), Bethany Joy Lenz (Haley), and 'James Lafferty' (Nathan) each directed an episode for the first time during season 6.
James Lafferty is the only regular cast member to be the actual teenager playing a high school student even though he's already 20 years old by the end of season two.
